The iOS 7 update process does not go smoothly for most iPhone and iPad users who experience errors when updating to iOS 7, including error 9006 in iTunes when trying to update.
Error 9006, or error 9006 as Apple defines it, is a common problem that users encounter when installing the iOS 7 update to iTunes, and it’s one we’ve seen before.
Apple provides several ways for users to fix iTunes Error 9006, some easy, some a little more advanced. We’re going to show you some things you can try to keep your iOS 7 update running and fix error 9006 issues that iTunes is throwing at you. \
iTunes error 9006 is a hassle for iOS 7 updaters.
If you get error 9006 while trying to update to iOS 7 in iTunes, the first thing you can try is to close iTunes and restart the process of checking for updates. This is not a guaranteed fix, but it has worked for several readers and Gotta Mobile team members. Plus it’s the easiest thing to try.
If that fails, Apple recommends turning off any third-party security software. If you have antivirus or firewall software running on the computer, this could be behind the problem. Apple says uninstall, but turning it off at least on the first try should be enough.
Next up, Apple says to check the default packet size. Chances are, most PCs belong to users who didn’t change this in the first place, so it’s okay to jump to the next step. If you want, Apple provides instructions to reset it.
Users can also log into their routers and make sure ports 80 and 443 are allowed. Again, most users who have not made changes or are not in a business network do not need to worry about this step.
Check any firewall software to make sure albert.apple.com or phobos.apple.com is not blocked. This varies by software application.
The step most of you can do would be to delete the partial download of iOS 7 which will force iTunes to restart the process. This is where the file resides on Windows and Mac.
Windows 7 and Vista (possibly 8) – C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\
Windows XP – C:\Documents and Settings\[username]\Application Data\Apple Computer\iTunes\
To quickly access the AppData folder, click on its icon and then type it in the search bar and press .
Mac OS X – ~/Library/iTunes/ (the “~” sign represents your Home directory)
While in this folder, look for a folder that says iPhone Software Updates, iPad Software Updates, or iPod Software Updates, depending on the device you’re using.
If that doesn’t work, try updating to iOS 7 on a different computer or over the air. To download iOS 7 directly to iPhone or iPad, go to
Finally, if all else fails, you can wait a day to install iOS 7. These problems usually occur when the Apple server is overloaded, so even if you complete all of these steps, it may not work.
